That would be harder to use reliably in the automated testing that this
feature is targeting.

With this mechanism, it is guaranteed that both processes notice when
the other dies because the connection gets disconnected. There's never a
time period where one process listens for a connection from a process
that might have died already, or never got started.

It's also easier that the scripts calling qemu only need to deal with
one process, as before, and just need to pass some additional
parameters.

Can we agree that both usage models are valid and thus support both?
